Question

If a 10-foot by 10-foot garden is enlarged by adding 2 feet to the length and 1 foot to the width, by how many square feet will the area of the garden increase?

O 10
O 11
O 20
O 32

Answer 1

Answer: 32 ft²

Explanation:

First, we will find the area of the original garden. We can use the formula A = LW to solve.

A = LW

A = (10 ft)(10 ft)

A = 100 ft²

Next, we will find the area of the new garden. Again, we will use A = LW to solve.

A = LW

A = (10 ft + 2 ft)(10 ft + 1 ft)

A = (12 ft)(11 ft)

A = 132 ft²

Lastly, we will subtract.

132 ft² - 100 ft² = 32 ft²

The garden's area will increase by 32 ft².
